Sound flow can also be used to "capture" the sounds of animals and analyze various complex sound waves.

For example, scientists draw the frequency of sound waves emitted by marine animals into various maps to identify their species. One day, humans may even understand how dolphins communicate through sound flow.

There are few people in the world who play music streaming.

I asked: "Do you understand the study of sound and flow?"

Yiwu said: "This is my profession."

Xu Erge and Meng Xiaoshuai both came to watch.

We borrowed a solar light absorbing panel from Bai Xinxin and carried it to a place far away from the camp. Then, we dug up some sand. Meng Xiaoshuai took the initiative to contribute her pair of stockings to sift the sand.

Finally, the dress dance evenly sprinkles those very fine sand onto the smooth absorber plate and lets us all leave. Any subtle sound will cause the pattern to change.

The dancer finally got a place to work, and she worked happily and focused.

We returned to the camp, introduced the situation to others, and told everyone not to move around and not to speak out. So everyone turned into wooden men.
Chapter completed!
